LiChrosolv® hypergrade is accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionization methods (ESI/APCI - positive and negative mode). Thanks to their low level of ionic background and low ion suppression, LiChrosolv® hypergrade solvents provide high reproducibility and high ionization efficiency. The packaging material has been improved to meet LC-MS quality requirements perfectly.Methanol hypergrade for LC-MS LiChrosolv®. CAS 67-56-1, chemical formula CH₃OH, molar mass 32.04 g/mol.Simpan pada +5°C hingga +30°C.
